Yeah, if you mean "detail on the planet" and not just resolve the planet from its star, then it's completely infeasible. The current 30m-class telescopes that are under development (ie www.tmt.org) in combination with high-contrast adaptive optics will make it possible to see earth-size planets, if I'm not mistaken, but not to resolve detail on their surface.
